Regarding high CPU usage when screen turns off.

I might have had a real casualty of this bug.  An 18 day old HP Pavilion
g6 failed after being left unattended for about 1 hour while running
Ubuntu.  The laptop was on a hard smooth surface in an air conditioned
environment.  It was found fan running, warm to the touch and screen
completely black.  Nothing could be done to exit this state. The failed
laptop was returned to a Compaq facility where I expect they are intent
on finding the root cause of failure (I do not believe this was a repair
facility).

The replacement HP Pavilion g6 (a slightly different model) is also warm
to the touch when the screen turns off.  Leading me to this bug report.
Conclusions, the problems stated here may be the secondary cause of the
first laptop's failure.  The primary cause of course would be the
laptop's inability to sustain high CPU usage.

(Some) information from the 2nd laptop:
